IH5142CJE

Analog Switches, Multiplexers, Demultiplexers Overview

The IH5142CJE is a single-channel analog switch manufactured by Harris Corporation, belonging to the IH5140 series. It features a normally-open (SPST-NO) configuration with a maximum on-resistance of 100 ohms and a channel-to-channel matching of 5 ohms. The device operates on dual supply voltages ranging from ±4.5V to ±18V. Key electrical specifications include a maximum charge injection of 15pC and an off-state leakage current of 100nA. Switching times are specified at a maximum of 150ns for turn-on and 125ns for turn-off. It is housed in a 16-SOIC surface-mount package and supports an operating temperature range of 0°C to 70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential obsolescence status. Confirm RoHS compliance requirements against specific project standards, as historical batches may not meet current environmental directives. Validate package marking and date codes to ensure compatibility with assembly processes and storage conditions.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a single-pole single-throw switch with 100-ohm on-resistance is required within the ±4.5V to ±18V supply range. Ensure the 16-SOIC package fits the PCB layout constraints. Consider the 15pC charge injection limit for high-precision analog signals. Verify that the 0°C to 70°C industrial temperature range meets the operational environment requirements.

Analog Switches, Multiplexers, Demultiplexers Part Context

The IH5142CJE is part of the Harris IH5140 series of analog switches, which also includes variants like the IH5140CWE. This series provides general-purpose analog switching solutions with consistent electrical performance across the family. Harris Corporation, later acquired by Intersil and subsequently Analog Devices, produced these components for industrial and commercial electronic applications.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Check for pin-compatible alternatives from Analog Devices or other manufacturers offering similar SPST-NO specifications. Verify that replacement parts match the 100-ohm on-resistance, 15pC charge injection, and 16-SOIC package dimensions. Ensure voltage ranges and temperature specifications align with the original design requirements.
